About C74

C74 is the ICD-10-CM diagnosis code for malignant neoplasm of adrenal gland. It belongs to block C73-C75 (malignant neoplasms of thyroid and other endocrine glands) and chapter 2 (neoplasms). It is a header code, so it can't be reported by itself; one of its 3 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: C74.0 (gland), C74.1 (gland) and C74.9 (gland).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
